Abstract

An integrated circuit comprising a plurality of modules (M, S) and a network (N) arranged for transferring messages between said modules (M, S) is provided, wherein a message issued by a first module (M) comprises first information indicative for a location of an addressed module within the network (N), and second information indicative for a location within the addressed module (S). Said integrated circuit further comprises at least one address translation means (AT) for arranging the first and the second information as a single address. Said address translation means (AT) is adapted to determine which module is addressed based on said single address, and the selected location of the addressed module (S) is determined based on said single address. Accordingly, the design of the first modules (M), i.e. master modules, can implemented independent of the address mapping to the addressed modules (S), i.e. the slave modules. Furthermore, a more efficient network resource utilization is achieved and this scheme is backward compatible with busses.

Claims

1. Integrated circuit comprising a plurality of modules and a network arranged for transferring messages between said modules wherein a message issued by a first module comprises first information indicative for a location of an addressed module within the network, and second information indicative for a location within the addressed module, the integrated circuit comprising

at least one address translation means for arranging the first and the second information as a single address,

wherein said address translation means is adapted to determine which module is addressed based on said single address, and

wherein the selected location of the addressed module is determined based on said single address.

2. Integrated circuit according to claim 1, further comprising:

at least one interface means associated to one of the modules for managing the communication between said associated module and the network,

wherein one of said address translation means is arranged in one of said interface means.

3. Integrated circuit according to claim 2, wherein

wherein said address translation means is arranged in said interface means associated to said first module.

4. Integrated circuit according to claim 2, wherein

said address translation means comprises an address mapping table.

5. Integrated circuit according to claim 4, wherein

said address mapping table contains fields for every channel of a connection, for network interface ports of a connection, and for local addresses in addressed modules.

6. Method for exchanging messages in an integrated circuit comprising a plurality of modules, the messages between the modules being exchanged via a network wherein a message issued by a module comprises first information indicative for a location of an addressed module within the network, and second information indicative for a location within the addressed module, the method including the steps of:

arranging the first and the second information as a single address,

determining which module is addressed based on said single address, and

determining the selected location of the addressed module based on said single address.
